عَن أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ رَضِيَ اللَّهُ عَنْهُمَا
تَقول قَامَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَطِيبًا فَذكر فتْنَة الْقَبْر الَّتِي يفتتن فِيهَا الْمَرْءُ فَلَمَّا ذَكَرَ ذَلِكَ ضَجَّ الْمُسْلِمُونَ ضَجَّةً
“God’s messenger arose to deliver an address in which he mentioned the trial a man will endure in the grave. On his mentioning that, the Muslims gave a shout of dismay.” Bukhari transmitted it thus, but Nasai added, “which prevented me from grasping what God’s messenger had said.
So when the clamour died down I said to a man near me, ‘God bless you, what did God’s messenger say at the end of his address?’ He replied that he said he had had a revelation that the trial they would endure in their graves would approximate to that of ad-Dajjal.”
